IMPROVEMENT IN PROCESSES OF CURRYING CALF-SKINS.

Specification forming part of Letters Patent No. 167,142, dated August24, 1875; application filed June 15, 1874.

To all whom it may concern:

Be it known that l, PRESTON WARE, Jr., of Boston, in the county ofSuffolk and State of Massachusetts, have invented certain Improvementsin Process of OurryingGalf- Skins, of which the following is aspecification:

This invention relates to leather for the manufacture of shoes, beingparticularly designed for the manufacture of leather which is to be madeup into shoes having rubber gores, such as Congress gaiters and thelike.

It has been found in practice that the oil or fatty material commonlyemployed in currying leather causes the gores to rot and become rapidlydestroyed when such leather is made up into shoes having such gores.

The object of my invention is to obviate this objection; and to this endconsists in curryin g the leather without oil or fatty matter, ashereinafter fully set forth.

In carrying out my invention, the skins are laid out in the usualmanner, but without stuffing. The skins are then curried without the useof oil or other fatty stuffin g, and are blackened or stained on thegrain side, and pebbled, diced, or otherwise finished. The skins may belaid out in the ordinary manner; but before stuffing the flanks oroutside edges are trimmed off and curried, without being subjected tothe stuffing process, and blackened or stained on the grain side, andfinished as usual. The centers, beingvaluable for the manufacture ofVamps and quarters, are stufl'ed and curried as usual.

By dispensing with the oil in currying, all liability of the gores torot is avoided when such leather is made up, resulting in a much moredurable shoe.

Having thus described my invention, what I claim, and desire to secureby Letters Patcut, is I As a new article of manufacture, leathercurried, blackened, and finished without oil or other fatty stuffing, asand for the purposes herein set forth.

PRESTON WARE, JR.
